You don't know what love is
Until you learn the meaning of the blues
Until you've lost a love you had to lose

You don't know what love is

You don't know how lips hurt
Until you've kissed and had to pay the cost
Until you've flipped your heart and you have
lost
You don't know what love is

Do you know how a lost hearts fears
The thought of reminiscing
And how lips that taste the tears
Lose their taste for kissing

You don't know how hearts burn
For love that cannot live yet never dies
Until you've faced each dawn with sleepless
eyes
You don't know what love is

Do you know how a lost hearts fears
The thought of reminiscing
And how lips that taste of tears
Ooh, they lose their taste for kissing

You don't know how hearts burn
For love that cannot live yet never dies
Until you've faced each dawn with sleepless
eyes
You don't know what love is

You don't know what love is
